QRB is app 1015km.

My second (and better) attempt to receive SAQ is documented in my video #21:

Stefan, I enjoy all your videos, but playing this old one had a special surprise for me. I was not aware of Grimeton. Upon researching it, I find that it is only a 33 min drive from where my relatives in Sweden live, that we have visited, and look forward to visiting again. So now we have added a visit to Grimeton to the itinerary for our next trip! Thanks for your many fine videos and sharing your knowledge and enthusiasm for the hobby. 73, de WB0DKT

Hi dr Glenn, Yes - good things are sometimes unknown but very near ....

Very interesting1 I did something similar last Christmas Eve using the little kit they sell at Grimeton, a loop antenna and a preamp, the BFO being a 555 IC. I am 1260 km away but I could hear the transmission very well, indoors even though the Skelton Tx is almost in line at 300 km on 22.1 khz.

Received from 1100 km from the transmitter using a frequency selective voltmeter, amazing.

Interesting, and very useful information. Also i didnt have a clue that Grimeton was located around here where i live in Sweden. It doesnt have a swedish-sounding name so assumed it was located in the US

Fascinating. I thought frequency had to be much higher to propagate as rf. Is this so for 1 hz, .01 hz, .0001 hz as well?

@dl7majstefan753 5 жыл бұрын

There is no absolute lower limit of the frequency for radiation. It´s depending upon the size of the antenna, the transmit power and the propagation. You can operate even with DC: The rotating magnetic core of earth is the transmitter, the earth itself is the antenna and the receiver is a compass; but modulation is a little bit difficult….smile.

Hello, I'm doing a replica of Your circuit to recieve SAQ this year (I will use a frame antenna with added, fixed capacity to make it work at lower frequencies). I have a question - is the resistor located far right (between BC413 and the output) is 47R or 47K? Thank You in advance for the anwser.
